  Re: [Aroid-l] Cataphill
From: Peter Boyce <phymatarum at gmail.com> on 2016.10.21 at 00:55:37
Hello David,

Taken from Flora of Thailand

cataphyll =E2=80=93 a modified leaf which lacks a blade and in appearance corresponds to a petiole
sheath; may be used to describe other leaf types whose technical names are defined by position
rather than form, e.g., prophylls are usually of cataphyll shape in Araceae, compare, prophyll.

prophyll =E2=80=93 the first leaf of a branch (or sympodial unit); in Araceae almost always a 2-keeled
cataphyll, often confused with cataphyll; cataphyll refers to a particular type of morphology
(reduced leaf), prophyll refers to the position of the leaf along a branch.

I am seeking a written description of the term cataphyll, including the function it performs.=C2=A0 Is it found only at the base of peduncles or also at the base of petioles?=C2=A0 Examples including images of each.=C2=A0 Is it only found in the Aroid plant family or elsewhere?

Thanks for your help.
